  mm/mglru: fix ineffective protection calculation (2024-07-17 21:08:55 -0700)

----------------------------------------------------------------
- 875fa64577da ("mm/hugetlb_vmemmap: fix race with speculative PFN
  walkers") is known to cause a performance regression
  (https://lore.kernel.org/all/3acefad9-96e5-4681-8014-827d6be71c7a@xxxxxxxxxxxxx/T/#mfa809800a7862fb5bdf834c6f71a3a5113eb83ff).
  Yu has a fix which I'll send along later via the hotfixes branch.

- In the series "mm: Avoid possible overflows in dirty throttling" Jan
  Kara addresses a couple of issues in the writeback throttling code.
  These fixes are also targetted at -stable kernels.

- Ryusuke Konishi's series "nilfs2: fix potential issues related to
  reserved inodes" does that.  This should actually be in the
  mm-nonmm-stable tree, along with the many other nilfs2 patches.  My bad.

- More folio conversions from Kefeng Wang in the series "mm: convert to
  folio_alloc_mpol()"

- Kemeng Shi has sent some cleanups to the writeback code in the series
  "Add helper functions to remove repeated code and improve readability of
  cgroup writeback"

- Kairui Song has made the swap code a little smaller and a little
  faster in the series "mm/swap: clean up and optimize swap cache index".

- In the series "mm/memory: cleanly support zeropage in
  vm_insert_page*(), vm_map_pages*() and vmf_insert_mixed()" David
  Hildenbrand has reworked the rather sketchy handling of the use of the
  zeropage in MAP_SHARED mappings.  I don't see any runtime effects here -
  more a cleanup/understandability/maintainablity thing.

- Dev Jain has improved selftests/mm/va_high_addr_switch.c's handling of
  higher addresses, for aarch64.  The (poorly named) series is
  "Restructure va_high_addr_switch".

- The core TLB handling code gets some cleanups and possible slight
  optimizations in Bang Li's series "Add update_mmu_tlb_range() to
  simplify code".

- Jane Chu has improved the handling of our
  fake-an-unrecoverable-memory-error testing feature MADV_HWPOISON in the
  series "Enhance soft hwpoison handling and injection".

- Jeff Johnson has sent a billion patches everywhere to add
  MODULE_DESCRIPTION() to everything.  Some landed in this pull.

- In the series "mm: cleanup MIGRATE_SYNC_NO_COPY mode", Kefeng Wang has
  simplified migration's use of hardware-offload memory copying.

- Yosry Ahmed performs more folio API conversions in his series "mm:
  zswap: trivial folio conversions".

- In the series "large folios swap-in: handle refault cases first",
  Chuanhua Han inches us forward in the handling of large pages in the
  swap code.  This is a cleanup and optimization, working toward the end
  objective of full support of large folio swapin/out.

- In the series "mm,swap: cleanup VMA based swap readahead window
  calculation", Huang Ying has contributed some cleanups and a possible
  fixlet to his VMA based swap readahead code.

- In the series "add mTHP support for anonymous shmem" Baolin Wang has
  taught anonymous shmem mappings to use multisize THP.  By default this
  is a no-op - users must opt in vis sysfs controls.  Dramatic
  improvements in pagefault latency are realized.

- David Hildenbrand has some cleanups to our remaining use of
  page_mapcount() in the series "fs/proc: move page_mapcount() to
  fs/proc/internal.h".

- David also has some highmem accounting cleanups in the series
  "mm/highmem: don't track highmem pages manually".

- Build-time fixes and cleanups from John Hubbard in the series
  "cleanups, fixes, and progress towards avoiding "make headers"".

- Cleanups and consolidation of the core pagemap handling from Barry
  Song in the series "mm: introduce pmd|pte_needs_soft_dirty_wp helpers
  and utilize them".

- Lance Yang's series "Reclaim lazyfree THP without splitting" has
  reduced the latency of the reclaim of pmd-mapped THPs under fairly
  common circumstances.  A 10x speedup is seen in a microbenchmark.

  It does this by punting to aother CPU but I guess that's a win unless
  all CPUs are pegged.

- hugetlb_cgroup cleanups from Xiu Jianfeng in the series
  "mm/hugetlb_cgroup: rework on cftypes".

- Miaohe Lin's series "Some cleanups for memory-failure" does just that
  thing.

- Is anyone reading this stuff?  If so, email me!

- Someone other than SeongJae has developed a DAMON feature in Honggyu
  Kim's series "DAMON based tiered memory management for CXL memory".
  This adds DAMON features which may be used to help determine the
  efficiency of our placement of CXL/PCIe attached DRAM.

- DAMON user API centralization and simplificatio work in SeongJae
  Park's series "mm/damon: introduce DAMON parameters online commit
  function".

- In the series "mm: page_type, zsmalloc and page_mapcount_reset()"
  David Hildenbrand does some maintenance work on zsmalloc - partially
  modernizing its use of pageframe fields.

- Kefeng Wang provides more folio conversions in the series "mm: remove
  page_maybe_dma_pinned() and page_mkclean()".

- More cleanup from David Hildenbrand, this time in the series
  "mm/memory_hotplug: use PageOffline() instead of PageReserved() for
  !ZONE_DEVICE".  It "enlightens memory hotplug more about PageOffline()
  pages" and permits the removal of some virtio-mem hacks.

- Barry Song's series "mm: clarify folio_add_new_anon_rmap() and
  __folio_add_anon_rmap()" is a cleanup to the anon folio handling in
  preparation for mTHP (multisize THP) swapin.

- Kefeng Wang's series "mm: improve clear and copy user folio"
  implements more folio conversions, this time in the area of large folio
  userspace copying.

- The series "Docs/mm/damon/maintaier-profile: document a mailing tool
  and community meetup series" tells people how to get better involved
  with other DAMON developers.  From SeongJae Park.

- A large series ("kmsan: Enable on s390") from Ilya Leoshkevich does
  that.

- David Hildenbrand sends along more cleanups, this time against the
  migration code.  The series is "mm/migrate: move NUMA hinting fault
  folio isolation + checks under PTL".

- Jan Kara has found quite a lot of strangenesses and minor errors in
  the readahead code.  He addresses this in the series "mm: Fix various
  readahead quirks".

- SeongJae Park's series "selftests/damon: test DAMOS tried regions and
  {min,max}_nr_regions" adds features and addresses errors in DAMON's self
  testing code.

- Gavin Shan has found a userspace-triggerable WARN in the pagecache
  code.  The series "mm/filemap: Limit page cache size to that supported
  by xarray" addresses this.  The series is marked cc:stable.

- Chengming Zhou's series "mm/ksm: cmp_and_merge_page() optimizations
  and cleanup" cleans up and slightly optimizes KSM.

- Roman Gushchin has separated the memcg-v1 and memcg-v2 code - lots of
  code motion.  The series (which also makes the memcg-v1 code
  Kconfigurable) are

  "mm: memcg: separate legacy cgroup v1 code and put under config
  option" and
  "mm: memcg: put cgroup v1-specific memcg data under CONFIG_MEMCG_V1"

- Dan Schatzberg's series "Add swappiness argument to memory.reclaim"
  adds an additional feature to this cgroup-v2 control file.

- The series "Userspace controls soft-offline pages" from Jiaqi Yan
  permits userspace to stop the kernel's automatic treatment of excessive
  correctable memory errors.  In order to permit userspace to monitor and
  handle this situation.

- Kefeng Wang's series "mm: migrate: support poison recover from migrate
  folio" teaches the kernel to appropriately handle migration from
  poisoned source folios rather than simply panicing.

- SeongJae Park's series "Docs/damon: minor fixups and improvements"
  does those things.

- In the series "mm/zsmalloc: change back to per-size_class lock"
  Chengming Zhou improves zsmalloc's scalability and memory utilization.

- Vivek Kasireddy's series "mm/gup: Introduce memfd_pin_folios() for
  pinning memfd folios" makes the GUP code use FOLL_PIN rather than bare
  refcount increments.  So these paes can first be moved aside if they
  reside in the movable zone or a CMA block.

- Andrii Nakryiko has added a binary ioctl()-based API to /proc/pid/maps
  for much faster reading of vma information.  The series is "query VMAs
  from /proc/<pid>/maps".

- In the series "mm: introduce per-order mTHP split counters" Lance Yang
  improves the kernel's presentation of developer information related to
  multisize THP splitting.

- Michael Ellerman has developed the series "Reimplement huge pages
  without hugepd on powerpc (8xx, e500, book3s/64)".  This permits
  userspace to use all available huge page sizes.

- In the series "revert unconditional slab and page allocator fault
  injection calls" Vlastimil Babka removes a performance-affecting and not
  very useful feature from slab fault injection.
